On March 17, 2021 at 20:06 UTC, a magnitude 4.2 shallow crustal earthquake struck near off the east coast of the Kamchatka Peninsula, Russia, at a depth of 10.0 km and coordinates 55.0060°, 163.2598°.
Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
